An uncommon sexual position, where the willing or usually unwilling participant is strapped into a lawn chair (the conventional method is duct tape but varied uses have included rope, electrical cords and Christmas lights.) The person is then flipped upside down and a hole is cut out of the seat, exposing the person's anus and/or genitalia, creating a make-shift glory hole for instant gratification. Common practice is to "chair" outside but the more bashful often commence the activity in the garage or pool house.

almost always useful. a person has to invest a great amount of faith into this object, for if it breaks (which is entirely possible) then one is putting the fact that they are currently not disabled at great risk ie. they could become disabled

Boy1: What you on bruv?
Boy2: A chair
Boy1: Isit? That's Sick
Boy2: Yeh, but I'm being careful though, 'cos if it breaks I could end up disabled.
Boy1: Mate, I wouldn't take the risk; I don't even sit on chairs anymore
